The Icon wireless guitar works great with both rock band and guitar hero. just make sure you put 4 AA batteries in the guitar.

Overview

The Wireless Guitar Evolution features a unique 10 fret button system for unmatched realism and full range of play. Hammer out powerful rhythm notes on the higher set of fret buttons and jump to the lower set to perform blistering solos.

"This unique design allows the Wii controller to be hidden in the base of the guitar while still allowing full use of the controller. Use the included USB dongle to allow full compatibility with RockBand, RockBand 2, Rock Revolution, Guitar Hero III and Guitar Hero: World Tour."
